NASA's Jet Propulsion Laboratory News and Features 10 Oct 2017, 20:25 UTC On Oct. 12 EDT (Oct. 11 PDT), a small asteroid designated 2012 TC4 will safely pass by Earth at a distance of approximately 26,000 miles (42,000 kilometers). This is a little over one tenth the distance to the Moon and just above the orbital altitude of communications satellites. This encounter with TC4 is being used by asteroid trackers around the world to test their ability to operate as a coordinated international asteroid warning network.
ESA Top News 10 Oct 2017, 07:46 UTC Talk about an image making your head spin: ESA astronaut Paolo Nespoli took this stunning image of NASA astronauts Randy Bresnik and Mark Vande Hai during last week’s spacewalk. During this excursion, the duo replaced part of the Station’s Canadarm2 robotic arm. The spacewalk took just under seven hours and saw the astronauts not only complete their main task but also accomplish some ‘get-ahead’ tasks. Spacewalks are intensive for both crewmembers and ground support, so any opportunity to get ahead is welcomed.
ESA Top News 9 Oct 2017, 07:00 UTC Mercury, the innermost planet of our Solar System is a grey, barren world to our human eyes. In stark contrast, this map shows a portion of the surface in a patchwork of colour, each shade corresponding to a different type of geological feature. The image is an excerpt from a detailed geological map that is the first complete geological survey of this region made using data from NASA’s Messenger mission, which orbited Mercury from 2011 to 2015. It covers a section in the planet’s northern hemisphere known to planetary geologists as the Victoria Quadrangle, and is centred on about 45ºW / 45ºN.
NASA's Jet Propulsion Laboratory News and Features 6 Oct 2017, 18:46 UTC The discovery of evidence for ancient sea-floor hydrothermal deposits on Mars identifies an area on the planet that may offer clues about the origin of life on Earth. A recent international report examines observations by NASA's Mars Reconnaissance Orbiter (MRO) of massive deposits in a basin on southern Mars. The authors interpret the data as evidence that these deposits were formed by heated water from a volcanically active part of the planet's crust entering the bottom of a large sea long ago.
NASA's Goddard Space Flight Center 6 Oct 2017, 13:45 UTC At a distance of just 160,000 light-years, the Large Magellanic Cloud is one of the Milky Way’s closest companions. It is also home to one of the largest and most intense regions of active star formation known to exist anywhere in our galactic neighborhood — the Tarantula Nebula. This NASA/ESA Hubble Space Telescope image shows both the spindly, spidery filaments of gas that inspired the region’s name, and the intriguing structure of stacked “bubbles” that forms the so-called Honeycomb Nebula (to the lower left).
ESA Space Science 6 Oct 2017, 13:00 UTC ESA and the Guggenheim Museum Bilbao, together with the BBK Foundation, have joined forces to celebrate the 20th anniversary of this emblematic arts centre. Chasmata is a pioneering journey to Mars through the medium of contemporary art, music and architecture.
ASI Agenzia Spaziale Italiana 6 Oct 2017, 11:06 UTC “Beep…beep…beep”. The signal emitted by Sputnik 1 launched by the Soviet Union sixty years ago during the night between 4 and 5 October marked the beginning of the race to space and of the use of satellites. But that's not all.
